SUBJECT:

REVISED FINAL SAFETY EVALUATION OF TECHNICAL SPECIFICATIONS TASK FORCE TRAVELER TSTF-564, REVISION 2, SAFETY LIMIT MCPR, USING THE CONSOLIDATED LINE ITEM IMPROVEMENT PROCESS

Dear Members of the Technical Specifications Task Force:

By letter dated October 24, 2018 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML18299A054), the U.S. Nuclear Regulatory Commission (NRC) approved Technical Specifications Task Force (TSTF) traveler TSTF-564, Revision 2, Safety Limit MCPR [Minimum Critical Power Ratio] (ADAMS Accession No. ML18297A361). As part of the approval, the NRC staff issued a final safety evaluation (SE) (ADAMS Accession No. ML18299A069).

The NRC staff discovered a typographical error in Section 3.3 on page 8 of the final SE as noted in redline/strikeout text below. The revised final SE correcting this error is enclosed. The revised final SE supersedes the final SE issued on October 24, 2018.

The NRC staff reviewed the information furnished by the TSTF and determined that the process for establishing the revised MCPR SL for mixed cores ensures that the limiting fuel types in the core will be evaluated and the limiting MCPR99.9%95/95 will be appropriately applied as the SL.

If you have any questions, please contact Michelle Honcharik at 301-415-1774 or via e-mail at Michelle.Honcharik@nrc.gov.

Sincerely, Victor Digitally signed by Victor Cusumano Cusumano Date: 2020.05.13 15:56:59
